Biography

Qin Lei joined Arizona State University as an assistant professor in January 2016. Prior to ASU, she was a senior electric engineer, ULC Robotics, Hauppauge, NY, April 2015-December 2015; an electric engineer, General Electric Research Center, Niskayuna, NY, 2012-2015; and an intern, United Technology Research Center, East Hartford, CT, March 2012-Oct.2012.

Her research interests include: motor drive for electrical vehicle, medium voltage inverter for PV, fast charging stations and high speed motor drive; control and stability in high penetrated microgrid; on board charger for electrical vehicle; DC-DC converter for data center application; and high frequency high voltage application based on SiC and GaN Devices. The website for Lei's lab is located at powerlab.engineering.asu.edu.

Lei is looking for Ph.D students for Fall 2020! Welcome to apply!
